Two days at the Recruitment Agency Expo. Dozens of conversations with agency owners, ops leaders, and rec tech providers. And one thing that kept coming up.
Not AI. Not the latest sourcing tool. Email. Specifically, the growing gap between the emails your fee earners are sending and the inbox those emails are supposed to reach.
The noise has dropped. Nobody was talking about silver bullets this year. People were asking harder questions: why have reply rates dropped? Why does our outreach feel like it’s working but the numbers say otherwise? Why are we burning through domains faster than we’re filling open mandates?
Those are the right questions. And the answers sit in an area most agencies have never properly looked at.
The email problem isn’t tools. It’s your reputation.
When reply rates drop, the instinct is to blame the platform. Change the tool, change the copy, try a different sequence. Sometimes that helps. Often it doesn’t.
The real issue is usually one of three things: poor domain reputation, inconsistent sending behaviour, or messages going out to lists that were never qualified in the first place.
In plain English: you’re sending emails people don’t care about, in a way that looks risky to spam filters. And inbox providers (Google and Microsoft) have been getting significantly better at spotting exactly that.
This matters more than most agency owners realise, because it affects every email you send. Not just cold outreach. BD emails to hiring managers. Follow-ups on live roles. Communications to candidates in your pipeline. If your domain reputation is damaged, all of it takes a hit.
Two models. Different outcomes.
Most agencies have settled into one of two approaches, often without consciously choosing one.
Volume-first — 30 to 50+ sending domains, AI-generated copy, high daily send volumes. The goal is to start as many conversations as possible, as quickly as possible. It can generate short-term reply spikes. But the shelf life is short. Domains burn out. Candidates and hiring managers see the same templated message from six different email addresses. Brand recognition takes a hit at exactly the moment your consultants are trying to build relationships.
Reputation-led — a single primary domain (or a closely managed secondary), properly configured DNS authentication, targeted lists, gradual sending volume, and messaging that’s actually relevant to the person receiving it. The ramp is slower. The results are more consistent. And crucially, the brand you’re building on LinkedIn, through referrals, and on your PSL relationships doesn’t get undermined by the outreach coming out of the same business.
The mistake isn’t choosing one model. The mistake is trying to do both at the same time, badly.
What your prospects actually see
I asked a group of senior hiring managers one question: what does most recruitment email look like?
Generic. Low effort. Obviously automated. Usually deleted before it’s read. Then I asked what they’d actually respond to.
“A reputable recruiter who clearly understands a problem we’re dealing with and shows they can actually help.”
That’s the whole brief. And no outreach tool in the world delivers that if the underlying message isn’t worth reading.
The metric you should care about
Open rates are broken. Email privacy protection and image pre-loading mean the number in your dashboard is unreliable. You might see a 45% open rate and think things are working. They might not be.
The metric that matters is reply rate, specifically a positive reply rate. Real interest. Actual conversations. Not automated bounce-backs or polite brush-offs.
If your positive reply rate is low, volume isn’t the fix. Reputation and relevance are.
Five things to check before your next campaign
1. Sort the technical foundation. SPF, DKIM, and DMARC need to be correctly configured on any domain you’re sending from. This isn’t optional anymore. Google and Yahoo made that clear in 2024, and inbox providers have continued tightening enforcement since.
2. Simplify what you’re sending. Fewer links, especially tracking redirects. No link shorteners. Clean formatting. If your email looks like a marketing broadcast, it gets treated like one.
3. Qualify your lists. A smaller, better-targeted list will always outperform a large, broad one. Sending to people who are genuinely likely to need what you offer (at the right time) is the most effective thing you can do for deliverability.
4. Rewrite the message. Lead with a specific observation or a real problem the recipient will recognise. Not your company, not your services, not a pitch. Show you understand their market. That’s what gets replies.
5. Keep sending behaviour consistent. Sudden volume spikes are a red flag to inbox providers. Consistent, gradual sending (even at lower volumes) builds trust with the algorithms that decide whether you land in the inbox or not.
The shift that’s already happening
The agencies seeing the best results in 2026 aren’t the ones with the biggest sending infrastructure. They’re the ones that have made a strategic decision to build outreach on reputation, relevance, and consistency… not volume and shortcuts.
That’s a longer game. But it’s the one that compounds. Better inbox placement. Higher-quality conversations. A domain and brand that still has value in two years’ time, not one that’s been burned through chasing short-term pipeline.
The question isn’t which tool you should be using. It’s why someone would reply to your email in the first place.
Get that right, and the deliverability tends to follow.
Serious about email?
If your reply rates are inconsistent, your open data feels unreliable, or you’re not sure what’s actually landing. We can run a quick deliverability audit. No jargon, no guesswork. Book a call.
